KEY-FASTENER.

' Specification of Letters Patent.

Patented July 2'7, 1909.

Application filed March 19, 1909. Serial No. 4845565.

To all whom it may concern:

Be it known that I, EARL J. RIPLEY, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented new and useful Improvements in Key Fasteners, of which thefollowing is a specification.

This invention relates to key fasteners, and particularly to a fastenerdesigned for use upon door locks of the mortise type for holding theinserted key against extraction or displacement.

The object of the invention is to provide a fastener of this characterwhich is simple of construction, may be easily applied for coaction withany ordinary mortise lock, and which may be thrown into engagement withthe stem of the inserted key to prevent the key from being jostled outwhen the door is forcibly closed, as well as to prevent displacement ofthe key by manipulation from the outer side of the door, thus making thelock practically burglar proof.

The invention consists of the features of construction, combination andarrangement tion through the door and face plate showing the fastener inengaging position.

Referring to the drawing, 1 designates a portion of the free edge of adoor provided with any suitable type of mortise lock 2, and 3 designatesthe inner face plate of the lock provided with an opening 4 for thepassage of the shank of the latch bolt knob 5 and with a keyhole 6.

7 designates the key which is inserted through the keyhole 6 from theinner side of the door and, as shown in Fig. 1, is turned to a positionto project the locking bolt 8.

In accordance with my invention, a recess 9 is formed in the inner faceof the door and covered by the plate 3. Within this recess is arrangedthe fastening device, which comprises a lever 10 intermediately mountedupon a pivot pin, bolt or rivet 11 carried by the plate 3. The lower endof the lever forms a locking arm 12 widened at its lower end andtransversely slotted to provide a forked or bifurcated engaging member13 to receive and engage the stem of the key 7. The upper end of thelever forms an operating arm 14 bifurcated or forked at its upper end toprovide a longitudinal slot 15 in which is fitted a stem 16 projectingexteriorly through and movable in a horizontal trans verse slot 17 inthe plate 3 and provided at its outer end with a button or finger piece18. By means of this button or finger piece the lever may be swungtransversely of the plate on its pivot 11 to swing the engaging member13 into and outof engagement with the stem of the inserted key 7, theslot 15 permitting the button to move horizontally while the leverswings in'its prescribed arc. The said slot 15 also permitsthe stem tobe adjusted downwardly to engage depressed offsets or looking notches 19at the ends of the slots 17, by which thelever may be locked in itsprojected andretracted positions. i

It will be seen from the foregoing description that when it is desiredto fasten the key 7 against rotation and displacement, it is simplynecessary to move the button 18 to the right hand end of the slot 17 anddepress its stem into the adjacent notch 19, by which the member 13 willbe thrown into engagement with the key to fasten the same from thekeyhole when the door is slammed to or turned and forced out of thekeyhole by an implement introduced from the outside of the door. Henceby merely fastening the key in the manner described the lock may be madeas far burglar roof as it is possible to make locks of this 0 iaracter.By sim 1y moving the knob 18 to the opposite end 0 the slot 17, thefastening lever may be retracted to per mit turning of the key to unlockthe door or withdrawal of the key from the lock. My invention may bereadily and conveniently applied to any door for use in connection withany ordinary mortise lock, and its advantages will accordingly beappreciated.

Having thus fully described the invention, what is claimed as new, is

The combination with a door having a mortise lock and rovided on itsinner face with a recess, of a face plate covering said recess andprovided with a keyhole and a horizontal slot above the same, said slotbeing formed with end offsets, apivoted locking device mounted upon theplate within the recess and having a key engaging end and an operatingarm, said key engaging end being e5 movement so that it cannot be jostled out of 1 provided With a laterally extending slot and projection,by which it may be manipulated,

the end of the 0 erating arm having a longisubstantially as described.10 tudinal slot, an an operating stem movable In testimony whereof Iafiix my signatur in the horizontal slot of the face plate and inpresence of two Witnesses. 1 adapted to engage the ofi'sets thereof,said EARL J.
